Acid alpha-Glucosidase (GAA or Acid Maltase) Assay Kit                                                                                                                         Price

Product Description: Glycogen storage disease (GSD) type II, or Pompe disease, is a multisystem disorder, and is the prototype of an inborn
lysosomal storage disease (LSD). The affected enzyme is lysosomal acid alpha-glucosidase (GAA or acid maltase), which is capable of degrading
alpha-1,4 and -1,6 glycosidic bonds. Since lysosomes are present in nearly all cell types, deficiency in lysosomal GAA can affect nearly all
organs. GSD type II patients may exhibit a wide range of clinical presentations. Rapid buildup of glycogen in skeletal muscle and the heart is
frequently observed. Most severe is the classic infantile-onset disease with prominent cardiomegaly and hypotonia with death due to
cardiorespiratory failure usually before 2 years of age. Late-onset type II GSD also exists, which is a slowly progressive myopathic disease
involving predominantly skeletal muscle. As the disease progresses, breathing problems can lead to respiratory failure. Recombinant GAA protein
(Lumizyme) is being used as therapy for the disease. The GAA assay is based on the hydrolysis of o-nitrophenyl-alpha-D-glucopyranoside,
resulting in increased absorbance at 405 nm (extinction coefficient= 18 mM-1cm-1), allowing for sensitive and quantitative assay of GAA enzyme
activity present in tissue/cell lysates and biological fluids. Kit components are stable for at least 1 year if stored and handled properly.
